Microfilm is a method of storing documents and images on a small film, typically 16mm or 35mm in size. This technology allows large amounts of information to be condensed into a compact format, making it easier to store and manage. Microfilm is often used in libraries, archives, and research institutions to preserve historical documents and records. To access the information on microfilm, specialized machines called microfilm readers are used. These devices magnify the images on the film, allowing users to view and print the documents. Microfilm is an important tool for preserving the past, as it helps maintain records for future generations.
